+*This Action currently can't be used in conjunction with pull requests of forks. See [issue #25](https://github.com/stefanzweifel/git-auto-commit-action/issues/25) for more information.*
 
 ## Usage
 
+**Note:** This Action requires that you use `action/checkout@v2` or above to checkout your repository.
+
 Add the following step at the end of your job.
 
 ```yaml
-- uses: stefanzweifel/git-auto-commit-action@v2.3.0

-    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
-```
 
-You **do not** have to create a new secret called `GITHUB_TOKEN` in your repository. `GITHUB_TOKEN` is a special token GitHub creates automatically during an Action run. (See [the documentation](https://help.github.com/en/articles/virtual-environments-for-github-actions#creating-and-using-secrets-encrypted-variables) for details)
+    # Optional local file path to the repository

+    commit_author: Author <actions@github.com>
+
+    # Optional tag message. Will create and push a new tag to the remote repository
+    tagging_message: 'v1.0.0'
+```
 
 The Action will only commit files back, if changes are available. The resulting commit **will not trigger** another GitHub Actions Workflow run!
 
-It is recommended to use this Action in Workflows which listen to the `pull_request` event. If you want to use the Action on other events, you have to hardcode the value for `branch` as `github.head_ref` is only available in Pull Requests.
+We recommend to use this Action in Workflows, which listen to the `pull_request` event. You can then use the option `branch: ${{ github.head_ref }}` to set up the branch name correctly.
+If you don't pass a branch name, the Action will try to push the commit to a branch with the same name, as with which the repo has been checked out.
 
 ## Example Usage
 
-This Action will only work, if the job in your workflow changes project files.
+This Action will only work, if the job in your Workflow changes files.
 The most common use case for this, is when you're running a Linter or Code-Style fixer on GitHub Actions.
 
 In this example I'm running `php-cs-fixer` in a PHP project.
 
+### Example on `pull_request` event
 
 ```yaml
 name: php-cs-fixer
 
-on:
-  pull_request:
-    paths:
-    - '**.php'
+on: pull_request
 
 jobs:
   php-cs-fixer:
     runs-on: ubuntu-latest
 
     steps:
-    - uses: actions/checkout@v1
+    - uses: actions/checkout@v2
       with:
-        fetch-depth: 1
+        ref: ${{ github.head_ref }}
 
     - name: Run php-cs-fixer

+
+## Outputs
+You can use these outputs to trigger other Actions in your Workflow run based on the result of `git-auto-commit-action`.
+
+- `changes_detected`: Returns either "true" or "false" if the repository was dirty and files have changed.
+
+## Troubleshooting
+
+### Can't push commit to repository
+If your Workflow can't push the commit to the repository because of authentication issues, please update your Workflow configuration and usage of [`actions/checkout`](https://github.com/actions/checkout#usage). (Updating the `token` value with a Personal Access Token should fix your issues)
+
+### Commit of this Action does not trigger a new Workflow run
+As mentioned in the [Usage](#Usage) section, the commit created by this Action **will not trigger** a new Workflow run automatically.
+
+This is due to limitations set up by GitHub:
+
+> An action in a workflow run can't trigger a new workflow run. For example, if an action pushes code using the repository's GITHUB_TOKEN, a new workflow will not run even when the repository contains a workflow configured to run when push events occur.
+[Source](https://help.github.com/en/actions/reference/events-that-trigger-workflows)
+
+You can change this by creating a new [Personal Access Token (PAT)](https://github.com/settings/tokens/new), storing the token as a secret in your repository and then passing the new token to the [`actions/checkout`](https://github.com/actions/checkout#usage) Action.
+
+#### Example Workflow
+
+```yaml
+name: php-cs-fixer
+
+on: push
+
+jobs:
+  php-cs-fixer:
+    runs-on: ubuntu-latest
+
+    steps:
+    - uses: actions/checkout@v2
+      with:
+        token: ${{ secrets.PAT_TOKEN }}
+
+    - name: Run php-cs-fixer

+    - uses: stefanzweifel/git-auto-commit-action@v4.1.2
+      with:
+        commit_message: Apply php-cs-fixer changes
+```
+
+## Known Issues
+
+- GitHub currently prohibits Actions like this to push changes from a fork to the upstream repository. See [issue #25](https://github.com/stefanzweifel/git-auto-commit-action/issues/25) for more information.
